Answer:
340.
Explanation:
First lets just write out the problem
6 ( x - 2) (x - 3) +4 (x - 2 ) (x - 5)
we substitute x for -3
6 ( -3 -2) ( -3 -3) +4 ( -3 -2) (-3 -5)
now following PEMDAS we solve the inside of the ()'s
6 ( - 5 ) ( - 6 ) +4 ( -5 ) ( - 8 )
PEMDAS Requires us to Multiply first, so we do that
6 x -5 x -6 = 180
-5 x -8 = 40
We now have
180 + 4 x 40
Still multiplying first
180 + 160
and now to finish it off, at them together
340.
